REWIREABLE SCREN.

Application filed October 14, 1926. Serial No. 416,864.

To all whom t may concer/m: y

Be itv kno-wn that I, HENRY HIGGIN, of Newport, in the' county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Rewireable Screens, of which the following is a full, clear, and exact description, reference being had lto the drawings forming part of this specification.

It is the object of myinvention to make a strong and simple structure of the above character. without excessive welding, and

capable of taking throughout a. baked enamel of high quality. Among other things' I provide a folded metal frame for the screen which is held together without excessive spot welding, and this welding is done onlyat the corners.

The above object andother advantages to .be noted I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawin s,

Figure 1 is a etail corner elevation of a screen made according to my invention.

Figure 2 is a perspective View of a corner iron assembly.

Figure 3 isa perspective of one of the corner re-enforcing pieces.

Figure 4 is a perspective view of one end of a frame piece cut ready for use.

Figure 5 is a detail section taken through a screen illustrating the method ofretaining the screen wire.

The screen frame pieces are made of fairly heavy sheet metal bent into special form. so

, a short distance along the base, as at 7.

The lip 7 is n o where secured to the base, either by welding'or soldering, thereby saving expense in labor cost and permitting (as against a soldered product) of the use of high quality en amel, which when baked on at high temperature will last as long as the metal frame itself.

-The frame pieces are cutat the ends, as at 8, to form a half corner, and into each corner end is inserted a re-enforcing piece 9. The pieces S) consist of two sides and a base.y

- frame pieces so spot welded as at 10, 10, two welds being entirely sufficient.v I have found that when welded or otherwise secured in place these re-enforcing pieces taken together with the conformation of the frame pieces generally will result inl the formation of a substantially rigid, non-weaving frame piece.v

In assembling the screen frames, they are set together at the corners and corner braces 1l, 1l driven into the corner vof each two adjacent ends. The preferredform of corner brace comprises two oppositely curved angle pieces having inturned flanges l2, which are set together prior to driving them home into the frame pieces.

If it is desired to use rivets instead of spot welds at the corners, the frame pieces and corner .re-enforcements can be shipped in lengths, and cut andy assembled to size on the job. vAs illustrated in Figure 3, the re-enforcing pieces can be riveted throughpu'nched holes 13, and the rivet heads will be'cleared by theconcavity 14 `in the corner braces.

A spline 15 of any desired form is used to hold the screen wire v16 in place in the channels of the frames, as shown in Figure 5, in which the splines is held in place by a metal strip 17 driven into place after the splines are set.

It is at once apparent that the structure above described is simple to manufacture, and I have found screens so made to be vvery strong and substantially non-weaving. It is not necessary that theabutting flange and the base of the frame pieces should be secured together, vas rigidity at the corners is all that I have found necessary.

Having thus describediny invention, what I claim as new and desire -to secure by-Letters Patent, is Y,

l. In a device of-the character described the combination of folded metal frame pieces formed by return bending of a. sheet of metal, and lapping but not securing it to the basel of said return bend, with a channel along the inner edge thereof, and re-enforcing pieces for the corners of said frame pieces having a base to be set at the lapped but unsecured portion `of the folded structure, and means for securing said re-enforcsecured fast to the base and top the said return bend and the baseV faced ing pieces immovably-in the frame pieces for the purpose described. e

2. Ina revvireabley metal screen a frame piece comprising ai hollow body formed by return bending of a. sheet of metal, and lapping4 but not. securingY it 'to the `base-ofthe said return bend, and a channel along the inner edges thereof, and a re-enforcing piece sides being two sides, said at least of having a base and toward the lapped but unsecured portion.

3. In a` rewireable metal screen, ay frame piece `olded lfrom metal tV form a base, an

outer Wall, an inner Wall, y returnbend to the base and a lapping flange, said flange being unsecured to the base, and the base bent to form an outer channel Wall in oppo- HENRY, HrGGIN.
